Christianization was, in all likelihood, just as brutal of a process than Islamization. Let me explain why.

In Iran, we find at least 20,000 Zoroastrians in Yazd in unbroken patrilineal continuity to mobeds of Sassanian era. However, we do not find a single group worshiping European Sol Invictus, Mithras, or Germanic figures (e.g., Druids, Odin) preserving and maintaining traditions/cults, while in unbroken patrilineal continuity, dating to pre-Christian times. In fact, Europeans had to reconstruct the pagan beliefs because no extant cult existed.

I find it humorous whenever I see European nationalists describe themselves as Christian. In fact, you are more Semitic in spirit and mentality whenever you do this. Christianity is not indigenous to Europe. You should at the very least attempt to reconstruct your pre-Christian traditions, especially the cult of Sol Invictus, if you value your "European" heritage so dearly. It is pathetic that I know more about your histories and cultures before Christianity than you people do.

Islamization was a brutal process in Iran, don't get me wrong. Rashidun and Turks were both genocidal maniacs, but for some odd reason, we retained pocket communities that preserved Pre-Islamic beliefs whereas Europeans utterly failed at this. Note, Iran even had more pocket communities of Zoroastrians in Tabaristan, called "Paduspanid dynasty", and Shiraz until Safavid invasions of 15th century CE, which forced a brutal process of Shia conversion on the population. Regardless, at least a small community of Zoroastrians survived in Yazd, one that many Iranian nationalists value moreso than Islam.

Do you think Europeans just dropped their Indo-European myths and suddenly became Christian on their free will? You are deluded as fuck if that's what you believe, especially with figures like Charlemagne and more. If I saw an Iranian nationalist who called himself Muslim, I'd mock him too, so don't think I'm a cuck that will give you knucklehead American and European Christcucks a free pass.

Go back to worshiping a megalomaniac rabbi, one that I take glee in his crucifixion; that pedophile, warmongerer Muhammad can join him on that cross too and both can eat shit in hell. Both Islam and Christianity are stupid.
